According to studies reported in the journal Medicine & Science in Sports & Exercise, avid or competitive cyclists are at increased risk for loss of bone density, making fractures due to falls more likely. This is because cycling is a low impact activity and doesn't put stress on bones that would make our bodies add density to them to compensate. Swimming is another sport that might make its participants suffer such a risk, but swimmers obviously don't have nearly the risk of a fall breaking a bone. The lower spine is particularly susceptible to this problem.

Athletes in sports like running and cross-country skiing aren't affected by this as they are forced to support their weight much more than cyclists are, making their bodies reinforce their bones with minerals.

Some other issues that might cause the problem are nutritional factors, as cyclists sweat out lots of important nutrients. There are possibly hormonal issues at play here, too.

The result could be an increased risk of osteopenia - lowered bone mineral density, or osteoporosis - basically osteopenia taken to the extreme. This is similar to the bone conditions encountered in elderly people but is happening in people much younger.

David (and I) would recommend that you mention this study to your doctor at your next visit, and see what sorts of solutions might be available. In the meantime, increased consumption of vitamin D and calcium can help.

No correction needed - this was mentioned in the article. I think it's safe to say that cycling commuters can be called "avid," and I also think that it's better to be safe than sorry. There's not some checkbox that you can fill out that says "I'm not a competitive cyclist, so I won't be having this issue."

If all you do for exercise is cycle, and you don't do any exercise that stresses the bones that they're talking about, like the back, then yes - you're more susceptible to this problem. It's simple physiology - if you don't use those parts of the body, they atrophy.

The Dispatch report that Columbus Rides Bikes shared on Facebook today is entitled "More crashes come with more bicycle traffic on dedicated lanes," and discusses the new lanes and the number of accidents that have happened there. None of these accidents/crashes has been fatal.

So... you can read the article and get the statistics. Here's a summary of them, though, with a quote from the article:
...the number of crashes has jumped. Between 2012 and 2015, there were five crashes involving bicycles on Summit between Hudson and East 5th Avenue.…

In a move that has left quite a few people stranded in Columbus, the ride-sharing company Car2Go has announced today that they're pulling out of the local market as of May 31.

This has got me more than a little pissed off and very inconvenienced.

There's no doubt - Car2Go improved the quality of my family's life for the past few years while they were active in town. As a one-car family where I rode my bike and took the bus most days, Car2Go filled in the gap nicely when we needed that extra set of wheels to get ourselves places.

Here's the news they sent out via their website today:

HELLO,
We’re writing to let you know that after careful consideration, we have made the difficult decision to discontinue car2go service in Columbus, effective May 31, 2018.

I've been out with the flu for a few days (no, I'm not oinking), and I missed this surprising post from Jeff Stephens of Consider Biking back on October 9th. Suffice to say that Jeff took some time to sit back and watch the behavior of our city's cyclists, and was dismayed at what he saw. I'm in complete agreement with Jeff on this issue. Simply too many Columbus cyclists do not obey the law. But let's look at the reasons that Jeff proposed in his commentary: Why are you riding this way? Are you so self-absorbed, that the world revolves around you? Are you just opportunistic since the bicycle gives you the opportunity to cheat traffic? Are you “expressing yourself” with your nonchalant coolness, hipness, whatever? Or, do you just not know any better? Do you just follow the example of the guy/gal in front of you because you’re new to urban bicycling? (I think it’s the latter.)Jeff's statement breaks the possible reasons for this behavior down into two extrem…
